FEEDING EGTTLE.

Application filed June 3,

T0 all whom it may concern.

Be it known that l, LEONARD Connnmen DAVIS, a British subject, residing at Frintonoil-Sea, in the county of Essex, England, have invented certain new and useful improvements in Feeding Bottles, (tor which I have filed an application in England June 2, 1920, Patent No. 152,594,) ot which the following is a specification.

This invention relates to feeding bottles for infants and has for its object to produce a feeding bottle formed in separable parts of which one part may serve as a cup-like receptacle adapted to withstand heat for use in preparing and heating the infants food.

It further has for its object to provide a bottle of which one part is formed as a cuplike receptacle that is free from projecting parts and is adapted to be easily and thor oughly cleaned.

A further object is to provide improved means whereby the separable parts may be readily and efficiently maintained in operative relation with an air-tight joint to form a complete feeding bottle.

These and further objects will be made clear in the following description aided by the accompanying drawing, in which Fig.1 is a side view partly in section of a feeding bottle and clamping device con structed in accordance with this invention and Fig. 2 is a back view showing more clearly the clamping device shown in 1.

Similar letters refer to similar parts throughout the two views.

in the drawing a, Z respectively designate the separable parts of the bottle. The part (2 comprises a domed cap of rigid transparent material (preferably glass) and is provided with a forwardly-extending neck 0 adapted to be fitted with a teat (not shown). The neck is inclined at about 45 degrees to the main axis of the bottle, so that the teat may be maintained at the correct angle for feeding a reclining infant when the bottle is inverted. On the upper wall of the neck 0 is formed a lump or thickening 6 so as to form a saddle between the bead of the neck a and the thickening 6 immediately above the main axis of the bottle.

The lower edge of the upper part a is adapted to fit loosely within the expanded mouth of the lower part b as shown, a flange or bead (Z being provided adjoining the edge of the upper member to prevent over-inser- Patented J an.

tion and also to form an abutment for an india rubber ring f adapted to be engaged between the said head and the expanded rim of the lower part Z). i

The lower part b comprises a cup-like vessel formed of fireproof china, earthenware. glass, aluminium or other metal which mav enameled or otherwise protected, and may oe graduated to measure the feed. It is essential that this part be formed of a material that is not damaged by heat so that it can be placed with safety on a or like stove to heat the food contained therein. In form it is free from corners or pro ections and has an unrestricted mouth and smooth finish. It is provided with two external lugs g on opposite sides which are pierced to admit the ends of the wire it. The parts a, b are illustrated as being oval in cross-section and the saddle between the neck 0, and thickening c is adapted to be positioned in line with and above the lu s g when the parts are assembled. In bot-b the parts a, 5 all angles are rounded. oif to facilitate cleansing.

The clamping device consists of a wire h bent as shown in Fig. 2 to form a VOlTG, the ends being inserted into the holes provided in the lugs g by drawing these ends apart and allowing them to spring back into position. This wire 72, is threaded through a roller Z: which is shaped to fit the saddle on the part a and is pierced eccentricallv at m as shown in Fig. l, and which is provided with an arm Z by means of which it may be rotated. The wire 71 is constructed of resilient material (such as steel.) and the roller 70 with its arm Z may be constructed of any suitable metal or other material. The arm is sho .=rn in raised position in Fig. 2 for the sake of clearness.

The operation of the device is as follows- Assuming the yoke h to be rotated clear or the mouth the cup-like receptacle Z the upper member a is placed in position together with the ring As the roller 70 is cccentrically mounted on the wire yoke 72, it rotated so as to give maximum inward cler nce whereupon the yoke can be moved up -i .o the position shown, the roller in its position of maximum inward clearance effectively clears the lump 6. The roller then oies the position shown in dotted lines i i. if new the roller is rotated into position shown in full lines by the arm Z, owing to the eccentricity of its mounting,

it presses the part a downwardly upon the part 5 and the said parts form an airtight joint owing to the provision of the rubber ring f which is thereby compressed and expanded laterally. The arm Z is rotated until it contacts with the lump 6 in which position the boring m of the roller has moved past its position of maximum separation from the lugs g, and the strain on the arms of the yoke, therefore, tends to maintain the parts in their locked position.

Qwing to the provison of a transparent upper part, the contents of the assembled bottle can be readily inspected, and owing to the form and construction of the lower part the latter can be readily used for mixing and heating liquid food. and readily cleaned after use by means of a clothinserted in the unrestricted mouth.

I claim 'l. A feeding-bottle formed intwo parts adapted to be fitted together and means for retaining the said parts in operative position comprising pierced lugs on one part, a wire yoke having its ends hingedly mounted in said lugs, a roller eccentrically mounted on the wire yoke, said roller being adapted to be engaged with an element of the surface of the other part.

2. A feeding-bottle formed in two parts, the upper part having a delivery neck, a bead on the rimof said neck, a lump on said neck spaced from said bead so as to form a saddle therebetween, pierced lugs on the lower part, a resilient wire yoke hingedly mounted in said lugs, a roller eccentrically mounted on said wire yoke, the said parts being adapted to be fitted together with the interposition of a resilient packing, the yoke being of such a size that when the parts are so fitted the roller in its position of maximum inward clearance can be swung over the lump and in its position of minimum inward clearance engages with the saddle to press the two parts resiliently together.

3. A feeding bottle, comprising a cupshaped vessel having an outturned rim, a cap having a rim portion adapted to engage the rim of the vessel, apacking ring adapted to fit between the rims, a member pivotallymounted on the vessel adapted to extend over and beyond the cap, and an element eccentrically and pivotally mounted on the member adapted to engage thecap and force it toward the vessel to compress the packing between the rims.

4. A feeding bottle, comprising a vessel. formed of fire-resistant material and having a bottom and side walls with an outwardly flaring upper edge portion, the contour'of the vessel includin the flaring upper edge portion being smooth and unbroken on the interior thereof, a-cap adapted to fit over the open upper end of the vessel having a head on the outer surface thereof adapted to engage the flaring portion of the vessel,

whereby the contour of the vessel and cap is even and free from sharp projections permit ting a thorough cleansing thereof, and means for holding the cap on the vessel. V In testimony whereof I aflix my si nature.
